BitTorrent announced the availability Wednesday of a preliminary, test version of BitTorrent Bleep software, which will enable people to make calls (voice only) and send messages over the Internet without using a central server to direct traffic. Instead, users will find one another through groups of other users, with no records of the calls or texts stored anywhere along the way.

Once a connection is made for a call or text, the communication travels directly between the two computers involved. That peer-to-peer approach also defies mass surveillance. Granted, it doesn't pay to underestimate the National Security Agency's ability to monitor even well-hidden communications. But Bleep certainly makes the job harder than the most popular online calling and messaging apps do.
